MOVABLE HEADLIGHT-SUPPORT.

Application med Aam 1s, 1912, Aserial No. 691,253.

T o all whom, it may concern:

Be it known that I.l NED GENSEMER Knut- 'ni-. i.. a citizen of the UnitedStates, residing at Pine Grove, in the county of Schuylkill and State of Pennsylvania. have invented new and useful Improvements in Movable Headlight-Supports. of which the following is a specification.

My invention relates to movable headlight supports for automobiles, and in particular to supports of this type which `are automatically operated by the steering mech- :mism of the machine. i

An object of the invention isthe provision of means for operating the headlight supports which will be rendered operable only upon considerable turning movement of the machine.

hcn an automobile isbeing driven along a direct narrow road, frequent. slight deviationsin the course of thel machine are necessary to avoid obstructions or roadway de` fet-ts. and yet it is not desirable to havethe rays of light from the headlights deflected out. of the general course of travel. On

the other hand when the machine is rounding a curve it is necessary that the-lamps should throwA their rays in the general direction of travel, which, in this case is not straight ahead.

It is, therefore, the objectof my invention to provide means for automatically controlling the movement of the headlights in direct accordance with the degree of change 'in the machines course.- r

Further objects of the invention will appear as the followingspecific description is` read in connection with the accompanying drawings, which form a part o'f this yspecification, in which Figure 1A is a front elevation of the device.' Fig. 2 is a side elevation. Fig. 3 is a brokenplan view showing the steering mechanism set for straight forward mot-ion of the machine. Fig. 4 is a similarview showing the steering mechanism set for slight change, in the course. Fig. 5 is a similar View showing the steering mechanism adjusted for sufficient change in direction to the right to turn the lamps accordingly. Fig. (3 is a similar View showing the steering mechanism set for turning to the left sufficiently to operate the lamps. Fig. 7 is a fragmentary front elevation of one of the lamp supporting shafts, showextremity ing means for attaching the lamp operating member to the yoke member thereon. Fig. 8 is a detail, horizontal sectional View through the yoke member and shaft, showing the operating member broken away.

In the drawings the'numerals 1 and 2 designate the sidemembers ofthe chassis of the machine. Mounted upon the member 1 is a bearing bracket 3.' A shaft 4 is rotatably mounted in the vertical opening -5 of the bracket?) and is provided at its upper extremity with the lamp supporting bracket arms 6. A yokemember 7 is rigidly secured to the shaft 4 so as to bearpupon the upper surface 8 of the bearing bracket This yoke member is positioned. so. that a vertical -plane passing longitudinally through the same will intersect. at an acute angle the vertical plane in which the bracket' arms ('lie. A lamp operating member 8 has its reduced cylindrical forward end 8a rotatably mounted within an opening 8b in the web portion 7*L of the yoke member 7, and is secured in this position with its shoulder 8c abutting the said web by means of an adjustable' nut 7b threaded on to the end of its threaded portion of the member 8 is curved as at 9 and provided'on its inner surface with a socket 10 for the recept-ion of a ball 11 is provided with a ball 13 adapted to heA received by a socket 14 on the inner surface of the curved portion 15 of a second lamp operating member 16. -The forwardly extending portion 17 of this member 1G is rotatably mounted in a similar yoke member 18 secured to the Vertical shaft 19 whose bracket arms 2O are adapted to support the other headlight. The shaft 19 is rotatably mounted in the vertical opening 21 of the bearing bracket 22 mounted on the frame member 2. A socket 23 is provided on the rear side of. the curved portion 9 of the operating member 8 and is adapted to receive a ball 24 formed on one extremity of a second connecting rod 25 whose opposite extremity is provided with a similar ball 26 adapted to be received by a socket 27 on the forward end of the reach bar 28 of the steering mechanism. An angular lateral extension 29 of the reach bar 28 hasitsfgrward ivotcd to the end of ana'rmgSO, extending aterally from thespindle operatextremity. The rearward ing arm 31, whoserearward extremity is in' turn pivoted to one end of the usual cross.

bar 32.

It will be seen by reference to Fig. 3' that when the machine is going straight forward,

Vthe curved portions 9 and 15 of the lamp operating membersS and 16 respectively will extend upwardly in nearly vertical positions. When the reach bar 28 of the steering mechanism `is thrown forward in v order to turn the wheels to the right through forward by the socket 27.

the medium of the arms 30 and 3l, the ball 26 on the connecting -rod 25 will be forced The'ball 24 on the .opposite end of the rod will act against the socket 23 so as to force the upturned portion 9 of the operating member drawing, 'limited operation of the steeringv 8 forward, its forward extremity thereby rotating within the yoke member 7.

Through the medium of the connecting Vrod 12, the operating member 16 will be similarly actuated. As shown in Fig-.4 of the mechanism will simply tend to rotate the members S-andvl until'their curved portions 9 and 15 res ectively, lie in -a'horizontal plane. v Furt er operation will Vcause these operating members to oscillate forwardand thus' impart rotary motion to the lamp supporting shafts 4 and 19, as shown by Fi 5. When the reach bar 28 is operate in areverse direction, the members 8 3and 1 6 will be rotated within the yoke members 7 and 18 so that their curved porf tions 9 and 15 respectively will'fall backward into a""horizontal plane. Thus if the operation be' continued, these members 8 A impart oscillatory movement to the operating members upon further movement.

2. A device of the class described comprising a support, a pair of spaced bearing brackets carried by said support, a lamp supporting shaft rotatably mounted in each of said brackets, a yoke member carried by each supporting shaft, a pair of operating members each comprising a horizontal portion rotatably mounted in one of said yoke members and an uptu-rned vertical portion extending inwardly therefrom, a connecting rod disposedjbetween said operating members, a universal joint connecting one end of said connect-ing rod with the upturned end of the corresponding operating member, the universal joint connecting the opposite end of said rod with the upturned end of the other operating member, a second connecting rod having its-rearmost end connected by means of a universal joint with the forwardly extending reach bar of the steering mechanism, and a universal joint connecting the opposite end of the second connecting rod with the upturned end of the adjacent operating member, said second connecting rod being inclined upwardly and forwardly.

In testimony whereof, I aiix my signature in presence of two witnesses.
